摘要
某型涡轴发动机燃气涡轮盘件毛坯组织晶粒粗大问题一直困扰着该型发动机,通过对材料及其成型工艺的分析,采用了等温模锻工艺方案,进行了试验研究和结果分析,并成功运用于生产实践。
The gas turbine emifinished product's big crystal question always affects the use of a certain turbine engine.analysing the material and it's technological process,we choose the model forging technology programme in the same temperature.Through the experiment and the result analyse,it has be braught to bear the produce succeedly.
